Yes, but I'm not certain it's been launched yet. They demoed it with Knack but it definitely isn't in Knack at the moment. Those features are probably going to be patched in later and could be more to do with PSNow.

possibly one of the best features, ive been hoping that someone would inplement this last gen. would be the next step to single player games imo. basically a bunch of friends playing single player online, kinda like the old days where we had to pass the controller round.
